摘要:
在文物保护研究领域,保护材料的“可逆性”是经常争议的问题之一:什么样的材料是可逆性材料?能否定量地表达可逆性?可逆性材料渗入砖、石、陶等多孔性材质中还可取出来吗?可逆性材料老化以后的可逆率会如何变化等等。为了探索这一类基础理论问题,本实验室提出运用“可逆率”来定量地表征材料应用过程的可逆性,可逆率可以通过清除实验来测量。通过测定B72、氟橡胶、纯丙乳液、环氧树脂在釉面瓷片、光面大理石、山西砂岩、凝灰岩和四川沙岩表面的取出率,计算出了它们的可逆率。实验表明许多保护材料都有一定的可逆性,其可逆率的大小与被保护基底材料的孔隙率(吸水率)呈反比,也与清除剂的种类和清除工艺有关,同时保护材料的紫外光老化过程也会明显影响保护材料的可逆率。文物保护材料可逆率的测量将会是研究其功能和机理的重要方法。
Abstract:
The reversibility of the preservation materials is often the controversy focus in the field of cultural heritage conservation: what kinds of materials are reversible materials? How to quantitatively express the reversible? Are reversible materials also desirable when penetrated into the microporous of brick, stone, clay,and other porous materials? How to change reversible rate after aging?In order to explore these basic theoretical problems,this work proposes that we can use the “reversible rate” to quantitatively character the reversibility of the preservation materials in the application process and the reversible rate can be measured through the clearance experiment. The reversible rate is experimentally measured by the Paraloid B72, fluorine rubber, acrylic emulsion and epoxy resin on the surface of glazed tiles, glossy marble, Sichuan sandstone, tuff and Shanxi sandstone. The experimental results show that all of these materials has a certain degree of reversibility. The removal rate of the protective materials is inversely proportional with the porosity of the basal substrate, and relates with the removing technology and scavenger species. The ultraviolet aging process is also significantly affecting the removal rate. The measurement technology of the reversible rate may be an important method to study the function and mechanism of cultural relic protection materials.
